Doppler Processing with Ultra-Wideband (UWB) Radar Revisited

Abstract

This technical note revisits previous work performed at the US Army Research Laboratory related to Doppler processing in radar systems using ultra-wideband (UWB) waveforms. In light of more recent research in this area, we demonstrate that exact reconstruction of the range and Doppler profiles is possible under UWB excitation, with the same Doppler resolution as that afforded by narrowband radar systems. Detailed theoretical derivations, as well as a simple numerical example, are included. Additionally, we discuss the computational aspects of this method and analyze the range and Doppler ambiguities introduced by the new processing scheme, showing its advantage in mitigating the Doppler grating lobes as compared to the conventional Doppler processing counterpart.
